Abstract: 1480372 Selective printing BUNKER RAMO CORP 19 July 1974 [6 Aug 1973] 32176/74 Heading B6F A printer with a moving type carriage 22 driven by a reversible motor 42, whose reversal changes the direction of movement of the carriage 22 includes sensors 50L, 50R detecting the presence of the carriage at the ends of its linewise movement and so causing reversal of the motor 42. The control system (not shown) responding to the sensors causes the motor 42, when printing is completed, to stop the carriage at the end of a traverse by reverse rotation of the motor 42 for sufficient time to halt the carriage 22. As shown the sensors 50L, 50R include light emitters 52L, 52R and photocells 54L, 54R between which shutters 28L, 28R respectively pass. Rubber bumpers 30L, 30R are provided on carriage rail 18. Printing may occur in one or both directions of movement of the carriage 22. The motor which may be D.C., bushless or stepping is controlled by a push-pull amplifier in turn controlled by an "enabling" flip flop and a "forward/reverse" flip flop which receive signals from sensors 50L, 50R and input print signals. One shot circuits provide the signal for the reverse rotation of the motor 42 to halt the carriage 22.

Abstract: 534,054. Hydraulic transmission of power. VICKERS, Inc. Dec. 20, 1939, No. 32631. Convention date, Dec. 24, 1938. [Class 69 (ii)] A hydraulic power transmission system for operating devices such as wing flaps, retractable landing gear &c. on aircraft of the kind in which the parts to be moved are connected to a fluid motor 36, Fig. 1, which is supplied with pressure fluid by a pump 10 and an accumulator 30 is arranged in the circuit as a reserve in case of failure of the motor for driving the pump 10, is constructed with valve control means for cutting off the supply of oil to the accumulator 30 when it is full, the oil returning via a pipe 40 to the tank 14. The valve connections are shown diagrammatically in Fig. 2 and the oil from the pump normally passes via a passage 18, check valve 46, port 22 to pipe 24 to the accumulator 30 or to the pressure side of a four-way valve 26 which connects to the motor 36. A pipe 42 leads from the valve 26 to the pipe 40 and the tank 14. When the pressure rises in pipe 24 to a certain value a. control valve 52 is moved to the left against the action of a spring 60 to connect the passage 18 and a port 44 to a port 38 leading to the tank thus byepassing the output of the pump to the tank 14. The valve 52 is moved under control of a four-way pilot valve 74 the spool 88 of which is itself controlled by a pressureresponsive valve 100 fitted with a piston 116 in a chamber connected by a restrictor 120 and a passage 118 to the port 22. The piston 116 is thus subject to the same pressure as the accumulator 30, and when the piston is raised against the action of a spring 125 in a housing, the valve opens up communication to the right hand end of the pilot valve 74 which is thus moved to the left and opens up communication from the pump inlet 44 to the passage 38 leading to pipe 40 and tank 14.

Vulcanizing-moulds; presses.-The apparatus of the parent Specification is modified by the addition of a device by which the opening of the moulds takes place in a predetermined order. A 'central chest 1 supported by brackets 2 on a base 3 has on each side a chest, 10, 11 the whole being held together by a bar 17 acting through springs 35. In the end 18 of the bar is journaled an eccentric 19 on a shaft 20 supported by the chest 10 and having a handle 25. When the handle is turned in a clockwise direction the bar 17 moves to the right, and through the bridge 32 and bolts 38 separates the chests 1 and 11. Further movement of the handle brings a stop 52 into contact with a part 51 of a clamp uniting the chests 1 and 10 and unhooks the clamp. A bolt 45 carried by the bar now engages a projection 46 on the chest 1 so that further rotation of the shaft 20 breaks the chest 10 from the chest 1. The bar 17 is then lifted through a slot out of engagement with the bridge 32 so that the chests 10, 11 may be moved manually to open them further. The chests 10, 11 are pivotally mounted as shown upon arms 6 hinged upon a vertical spindle mounted in brackets integral with the frame 2.

[Class 87 (ii).] Tubular articles are lined with a protective coating by coupling the tube to a driving head c and charging the lining material into a tubular receptacle h which is closed at the supply end after charging and moved axially as the tube a rotates. The tubular receptacle h works over a fixed but adjustable piston m and receives its charge from a supply pipe r by way of a funnel i to which a lid is applied after the required charge has been supplied. The receptacle is then turned about its axis through 180‹ and moved axially by gearing connected to the driving head c. After movement through the length of the tube, the saddle g, carrying the receptacle, contacts with the tailstock p after which the receptacle and the piston move together thus preventing further discharge of lining material.

[Class 97 (i)] The colour value of a liquid is determined by finding that length of light path through a basic solution which will give the same emergent light intensity as an air path of the same length, replacing this solution by the liquid or solution to be tested providing the same length of light path and comparing the intensity of the light emerging from the test solution with that of the light emerging from the basic solution. It is stated that if liquid is poured into a cylindrical vessel placed between a source of light and a light sensitive device the light reaching the sensitive device will at first decrease as the quantity of liquid increases and will then increase as more liquid is added until a point is reached at which the sensitive device receives the same amount of light as when the cylinder was empty. The apparatus consists of a cylindrical cell 3 enclosing a liquid column the length of which is determined as above described, the ends of the cell being closed by a flat plate 11 and a lens 12. A filling funnel 10 communicates with the cell. The cell is placed between a source of light 7 and a light-sensitive device 2 which is connected to a meter. A colour filter 9 is inserted between the cell and the light-sensitive element.
